Description

Inspired from Chinese user-mail which complains that host name in metrics name could only show the first part. However, their full host name is like "ambari.host12.yy" which means the first part "ambari" cannot identify anything.

We could support to let user record their full host name in the TaskManagerMetricGroup so that to identify metrics from different hosts.
